DETAILED DESCRIPTION

Disclosed herein are embodiments of covers, attachment systems forcovers, and methods of attaching a cover to the bed of, for example, atruck. In some embodiments, the covers can be tonneau covers, asdiscussed in detail below, but the type of cover does not limit thedisclosure.

In some embodiments, hangers, such as bow hangers, can be used to attacha tonneau cover, or tonneau, to a bed of a pickup truck. The tonneaucover can be hard or soft, or a mixture of hard portions and softportions. The relative rigidity of the tonneau cover does not limit thedisclosure. In some embodiments, the cover can be reduced in size byfolding or hinging for a hard cover, and rolling for a soft cover,though the method of reduction does not limit the disclosure. Therefore,the cover can extend over the length of the truck bed, or can becompacted into a storage position, thereby revealing the contents of thetruck bed for a user to more easily access. Because the tonneau covercan completely cover a truck bed, the tonneau cover can be used, forexample, to prevent sun or other environmental damage to cargo. Further,in some embodiments the tonneau cover can be locked onto the truck bed,such as on the gate of the truck bed, thereby increasing security of anycargo by preventing others from accessing a truck bed that is typicallyopen without the tonneau cover.

FIG. 1 shows a bed 100 of a truck which can be covered with a tonneaucover (the covered truck bed 100 shown in FIG. 2). A series of rails 102can be located on and can extend across the open top of the truck bed100. The rails 102 can be permanently attached to the bed 100, or can beremovable from the bed 100. As discussed in detail below, the rails 102can be attached on the truck bed 100 through the use of bow hanger andclamp assemblies 300. In some embodiments, the truck bed 100 can havegenerally parallel rails 102 along the length of the bed 100. There canbe 2, 3, 4, 5, 6, 7, 8 or more rails 102 and the number of rails 102does not limit the disclosure. Below the rails 102 is a generally flatsurface of the truck bed 100 which runs generally parallel to the bottomof the truck bed 100, this surface having a bottom lip 702 as discussedbelow.

Bows 200 can be located at the edges of segmented sections found in hardtonneau covers, though soft tonneau covers can be used as well. The bows200 can be associated with bow hanger and clamp assemblies, or bowhangers, 300. The bows 200 can be removably attached to the hanger 300.These hangers 300 can be used to attach the rails 102 to the sides of atruck bed 100. Further, the hangers 300 can attach a tonneau cover,through the use of bows 200 to the rails 102, thus attaching the tonneaucover to the truck bed 100. FIG. 2 illustrates a truck bed 100 with acover 101 over the bows 200. As shown, the cover 101 can be associatedwith the bows 200, thus allowing the cover 101 to provide a covering forthe bed 100.

As discussed in detail below, in some embodiments the bow hangers 300can be associated with and generally retained in the rails 102. This canbe seen in FIG. 3 and, as shown, the bow hanger 300 can contain a guide304, being generally T-shaped in some embodiments, which inserts intothe rails 102. The guide 304 can be generally a stem with a doubleflange member, though it could be other shapes as well and the shapedoes not limit the disclosure. When in the open configuration, the guide304 can slide within the internal structure of the rail 102.

FIG. 4 illustrates an embodiment of a bow hanger 300 in a closedconfiguration attached to a truck bed 300. As shown, guide 304 can beinserted into rail 102, thereby preventing or hindering movement of thebow hanger 300 in all directions other than in parallel with thedirection of the rail 102 so that the guide 304 slides within the rail102. To stabilize the bow hanger 300, and thus the tonneau cover, thebow hanger 300 can be closed, thus putting a generally vertical force onthe underside of a lip 702 of the truck bed 100. By closing the bowhanger 300, the rails 102, which can contain no other attachmentmechanism to the truck bed 100, can be mechanically attached to thetruck bed 100. Therefore, the bow hanger 300 can remain in place on therail 102 in the closed configuration. In some embodiments, after the bowhanger 300 is inserted into the rail 102 at a certain position, the bowhanger 300 may be mechanically fastened to the rail 102 so that thehanger 300 does not move relative to the rail 102, but the rail 102 canstill move relative to the truck bed 100.

In some embodiments, a plurality of bow hangers 300 can be used on thetruck bed 100. In some embodiments, 1, 2, 3, 4, 5, 6, 7, or more bowhangers 300 can be used on each side of the truck bed 100. In someembodiments, greater than 1, 2, 3, 4, or 5 bow hangers 300 can be usedon each side of the truck bed 100. In some embodiments, less than 2, 3,4, 5, 6, or 7 bow hangers 300 can be used on each side of the truck bed100. The number of hangers 300 used does not limit the disclosure. Insome embodiments, the same number of bow hangers 300 can be used on eachside of the truck bed 100. In some embodiments, a different number ofbow hangers 300 can be used on each side of the truck bed. In someembodiments, each bow hanger 300 can be associated with a portion of thetonneau cover. In some embodiments, not every bow hanger 300 isassociated with a portion of the tonneau cover.

In some embodiments, the bow hangers 300 can be movable along the rail102 when in an opened position. When in the closed position, the bowhangers 300 can be locked in a stationary where a user locks the bowhangers 300.

Bow Hanger

FIGS. 5-12 illustrate different viewpoints of an embodiment of a bowhanger 300. The bow hanger 300 can be formed with different attachmentmembers, a rail attachment member 302 to attach to the rail 102 and abow attachment member 308 to attach to at least one of the bows 200. Thebow hanger desirably also includes, a clamp portion 309 which can bemade up of the body 306, handle 310, pivot arm 510, and clamp engagementmechanism 312, though other parts can be used as well and the describedparts do not limit the disclosure. The clamp portion can be associatedwith members 302/308, which can be used to fix the bow hanger 300 (andthus the bow 200) to the rail 102.

As shown in FIG. 5, the first attachment member 302 can be used toattach to rails 102 sitting on a truck bed 100. The attachment member302 can be shaped generally like a triangular prism, though other shapescan be used as well and the shape of the attachment member 302 does notlimit the disclosure. For example, the attachment member 302 can berectangular shaped, square shaped, or irregularly shaped. In someembodiments, the attachment member 302 can contain hollow portions 303extending through the attachment member 302, as shown in FIG. 5. Thesehollow portions 303 can reduce the overall weight of the attachmentmember 302, while still retaining stability. In some embodiments, theattachment member 302 can be solid and not contain the hollow portions303. In some embodiments, the attachment member 302 can contain a guide304 configured to slide within the rails 102 of the truck bed 100, thusallowing the bow hanger 300 to slide along the plane of the rail 102.

In some embodiments, attachment member 302 can have a self tapping screw305 extend through it. As shown, the head of the self tapping screw 305can be located within the body of attachment member 302, for examplethrough an aperture, and the screw portion can extend away from theattachment member 302 in the direction of guide 304. In someembodiments, the screw 305 can extend through guide 304. Therefore, whenthe bow hanger 300 is located on a desired position on the rail 102, theself tapping screw 305 can be tightened to mechanically attach the bowhanger 300 to a fixed position with respect to the rail 102. In someembodiments, the self tapping screw 305 can extend from the attachmentmember 302 to relatively permanently attach the attachment member 302 toa rail 102. In some embodiments, the self tapping screw 305 can beremoved from a rail 102.

At the end opposite the guide 304, the attachment member 302 can beretained within a body 306. In some embodiments, the attachment member302 can be attached to a connecting member 500 which can be insertedinto a retaining body 306. In some embodiments, connecting member 500can be cylindrical, though the shape does not limit the disclosure. Thebody 306 can be shaped to accept the connecting member 500, though theshape of the body 306 does not limit the disclosure. In someembodiments, the connection member 500 can move along the axis of thebow 200 and the body 306, as shown by the arrow in FIG. 10. Theconnection member 500 can then be locked in place in the body 306, asdiscussed below. This can allow for flexibility in the clampingposition, and allows for ease in rotating to the stow position, asdiscussed below.

As mentioned, the end of the attachment member 302 inserted into thebody 306 can be sized and shaped to be retained within the body 306. Theattachment member 302 can extend out at different lengths from theretaining body 306, allowing for attachment to different truck beds 100.In some embodiments, the attachment member 302 can be movable in and outof the body 306. In some embodiments, in order to increase the length,the attachment member 302 can be removed and a longer or shorter membercould be inserted into the retaining body 306. In some embodiments,different lengths of attachment member 302 can be used at differentlocations of the truck bed 100.

In some embodiments, the body 306 can be formed from two differentpieces. The two pieces can be attached by an attachment element, such aswith rivets 307, shown in FIG. 9. However, the attachment mechanism doesnot limit the disclosure. In some embodiments, the body 306 can beopened. In some embodiments, the two body pieces can be permanentlyattached to one another. By having the two pieces, manufacturing of thebody 306 can be made easier.

Generally opposite attachment member 302 can be second attachment member308. This member 308 can be configured to attach to a tonneau cover. Forexample, the member 308 can be sized and configured to fit within hollowspaces in the bows 200 of a hard tonneau cover. However, the method ofattachment of the bow hanger and the tonneau cover does not limit thedisclosure, and any attachment means can be used. In some embodiments,the member 308 can be shaped like a rectangular prism, though the shapedoes not limit the disclosure. Member 308 can be inserted and retainedinto body 306. In some embodiments, members 302/308 and connectingmember 500 can be formed of a single piece, with the attachment member302/308 being on the ends and a generally connecting member 500attaching the ends.

In some embodiments, members 302/308 can each have a retaining mechanismfor attachment to their respective rail 102 and bows 200. For example,the members 302/308 can have a locking mechanism to retain the members302/308 in their respective location. In some embodiments, the members302/308 can have and indent, dip, or slot, for example, that resistsmovement but can be overcome if sufficient force is applied.

The body 306 can be attached to a handle 310 and clamp engagementmechanism 312. The handle can include a guard 316 configured to preventinsertion of a user's skin or fingers into any openings, thus reducingthe incidence of damage to a user's fingers. The guard 316 can extendaway from any joint on the bow hanger 300, such as the joint connectingthe handle 310 to the body 306. In some embodiments, handle 310, in theclosed position as shown in FIG. 9, can extend generally parallel tomembers 302/308. In some embodiments, the handle 310, in the closedposition, can extend at an angle away from the axis of members 302/308.The angle does not limit the disclosure.

In some embodiments, the handle 310 can extend away from the body 306,thereby providing sufficient room for a user to grip and hold the handle310. In some embodiments, the handle 310 can have a cushion, or othersoft material, attached for a user to hold. In some embodiments, thehandle 310 can be sized and shaped to easily fit within a user's hand.In some embodiments, the handle 310 can have a slip resistant surface,such as a rough surface or an attached increased friction surface, inorder to reduce slippage by a user when operating the bow hanger 300.

Both the handle 310 and body 306 can be attached to a clamp engagementmechanism 312. The clamp engagement mechanism 312 can be generally L, orC-shaped in structure, though the particular shape does not limit thedisclosure. In some embodiments, the corners of the L-shape can begenerally rounded. In some embodiments, the corner of the L-shape can beformed of two different bends 301 and a connecting segment 303, as shownin FIG. 9, thereby forming a more rounded shape for the clamp engagementmechanism 312.

In some embodiments, the clamp engagement mechanism 312 can vary inthickness across its body. For example, the lower arm 324 can be thickerthan the other parts of the arm, as the lower arm 324 can experiencemost of the load of the bow hanger during operation.

FIGS. 6 and 12 show an embodiment of a connection between the clampengagement mechanism 312 and the body 306. As shown, the body 306 canhave 2 segments 318 that fit within the gaps between 3 segments 320 ofthe clamp engagement mechanism 312. A connecting member 322 can thenpass through the segments, thus allowing the clamp engagement mechanism312 to rotate with respect to the body 306. This configuration can alsoprevent injury to a user if fingers were to be located in the area ofthe connection while the bow hanger 300 is being operating, as there isnot sufficient space for fingers to be caught in the connection betweenthe two parts. Further, by having the clamp engagement mechanism 312 bethicker than the body 306, more load can be applied to the clampengagement mechanism 312.

As shown in FIG. 10, at the end of the clamp engagement mechanism 312generally opposite of attachment to the body 306, the lower arm 324 canhave a rail retaining portion 314. The rail retaining portion can bemade up of an engagement member, such as pad 402, a body 404, and aposition adjustment member, such as screw 406, though other componentscan be used as well and the listed components do not limit thedisclosure.

The pad 402 can be made of a generally flexible or pliable material.Therefore, when the pad 402 presses against the bottom of lip 702, itwill not damage the lip 702. The pad 402 can mold or deform against thebottom of the lip 702 to give improved grip to the clamp engagementmechanism 312. Further, the pad 402 can be made of a slip resistantmaterial, or can be coated by a slip resistant material, which can allowthe pad 402 to remain in the desired position on the lip 702, even ifsome minimal forces were to act on the bow hanger 300. In someembodiments, the pad 402 can be generally circular, but the shape of thepad does not limit the disclosure, and square, triangular, orrectangular pads can be used as well.

The pad 402 can be located on and attached to a body portion 404, thoughthe attachment mechanism does not limit the disclosure. The body portion404 can be generally cylindrical, though the shape of the body portion404 does not limit the disclosure. In some embodiments, the body 404 canbe formed as a rectangular prism. The body portion 404 can be sized tofit within an aperture 802 (shown in FIG. 13) of the lower arm 324. Insome embodiments, the aperture 802 can contain a mating mechanism withthe lower portion of the body portion 404, thus preventing the bodyportion 404 from spinning in the aperture. In some embodiments, lowerarm 324 doesn't have an aperture 802 and the body portion 404 can reston the lower arm 324. Further discussion of the aperture 802 can befound below.

Below the lower arm 324, at the opposite side as the body portion 404,the rail retaining portion 314 can contain a screw 406. The screw 406can be used to adjust the positioning of the body 404, and thus the pad402. This can allow for different distances to separate the pad 402 fromthe bottom of attachment member 302, thereby allowing for attachment todifferent sized rails where the lip 702 can be located in differentvertical configurations.

In some embodiments, the screw 406 can advance adjust the position ofthe pad by about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1,1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, or 2.0 inches. In someembodiments, the screw can advance adjust the position of the pad bygreater than about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0,1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, or 2.0 inches. In someembodiments, the screw can advance adjust the position of the pad byless than about 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1,1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, or 2.0 inches. The distance ofadvancement by the screw 406 does not limit the disclosure.

FIGS. 13-14 illustrate an embodiment of the bow hanger 300 having anaperture 802 defined by generally cylindrical mating portion 804 whichis configured to accept generally cylindrical mating portion 806 of bodyportion 404. FIG. 13 shows a view of the lower arm 324 and FIG. 14 showsa view of body portion 404, the two views being in generally oppositedirection. These mating portion 804 can be configured to mate withmating portion 806 located on the body portion 404, so that the matingportion 806 is inserted within mating portion 806. Once inserted, thebody portion 404 can be locked in place at a respective position, thoughcan be generally rotated upon loosening of screw 406.

In some embodiments, the mating portions 804/806 can have a generallystair shaped internal structure, as shown in FIGS. 13 and 14.Accordingly, the body portions 804/806 fit against one another in thestair shaped internal structure. Once the screw 406 is loosened, thebody portion 404 can be rotated and moved to a different step in theinternal structure, which can change the vertical position of the pad402. The screw 406 can then be tightened, holding the body portion 404in place. The stair step internal structure can also prevent the bodyportion 404 from rotating unless a user so desires. In some embodiments,the mating portions 804/806 can have 1, 2, 3, 4, 5, or 6 stairs. In someembodiments, the mating portions 804/806 can have greater than 1, 2, 3,4, 5, or 6 stairs. In some embodiments, the mating portions 804/806 canhave less than 2, 3, 4, 5, or 6 stairs.

Self-Energizing Clamp Engagement Mechanism

In some embodiments, the clamp engagement mechanism 312 can beself-energizing. For example, a planar four-bar linkage can be used insome embodiments, allowing for stability and predictability in clamping.In some embodiments, a planar quadrilateral linkage can be used forself-energizing the clamp engagement mechanism 312. In some embodiments,a planar quadrilateral crank-rocker linkage can be used, which isdescribed below and shown in FIGS. 15A-C.

In the position shown in FIG. 15A, the clamp engagement mechanism 312 isin a self-energized position so that a load applied to the railretaining portion 314 of the clamp engagement mechanism 312 does notmove the clamp engagement mechanism 312 into the open position (as shownin FIG. 15C). For example, any force exerted downward onto the railretaining portion 314 of the clamp engagement mechanism 312 desirablywill increase the resistance of the clamp engagement mechanism 312 toopening. In some embodiments, the clamp engagement mechanism 312 wouldneed to move upward in a direction opposite the force on the clampengagement mechanism 312 before the clamp engagement mechanism 312 canopen. Therefore, if the clamp engagement mechanism 312 experienced alarge force, it would not pop open, which can be a significant problemfor other bow hangers in use. However, application of force onto thehandle 310 can open the clamp engagement mechanism 312.

In some embodiments, in the self-energized position there can be someslight rotational movement of the handle 310. For example, the handlecan rotate approximately 0.5, 1, 2, 3, 4, or 5 degrees without openingthe clamp engagement mechanism 312 or/or moving the clamp to a positionwhere the clamp is not still self-energized. In some embodiments, thehandle can rotate approximately less than 0.5, 1, 2, 3, 4, or 5 degreeswithout opening the clamp engagement mechanism 312 or/or moving theclamp to a position where the clamp is not still self-energized. Thisensures that the clamp remains self-energized even if the clamp handleis bumped and/or moves somewhat.

FIGS. 15A-C illustrate the bow hanger 300 in the closed/locked (FIG.15A), intermediate (FIG. 15B), and open (FIG. 15C) positions, therebyattaching the rail 102 to the truck bed 100.

As shown in FIG. 15A, the rail retaining portion 314 can be positionedapproximately perpendicular to attachment member 302. This position canlock the bow hanger 300 in place on a rail 102, and can lock the rail102 onto the lip 702. As discussed above, attachment member 302 can havedifferent lengths, and thus the location of the rail retaining portion314 relative to attachment member 302 can change based on the length ofattachment member 302.

As shown in FIG. 15A, hinge 506 is located “off line” from hinges502/504. Specifically, if a straight line was drawn between the centersof hinges 508/504, the center of hinge 506 would not be located on thatline. In FIG. 15A, hinge 506 is shown to be slightly above that line.This can promote the self-energizing functionality of the bow hanger300, as discussed below. Significantly, positions of the pivots of theclamp engagement mechanism 312 are positioned such that force acting onthe pad 402 in a direction which would otherwise tend to open the clampengagement mechanism 312, causes the portion of the handle 310surrounding the hinge 506 to be forced against an abutment surface 511of the body 306, which has the effect of “locking” the clamp engagementmechanism 312 in a clamped position.

It is not until the clamp engagement mechanism 312 has been moved toroughly to the position shown in FIG. 15B which is an intermediateposition between opening and closing, where force acting on the pad 402will tend to cause the portion of the handle 310 surrounding the hinge506 to be rotated away from the body 306 tending to open the clampengagement mechanism. As shown, the clamp engagement mechanism 312 canbe attached to the body 306 through a hinge 501. Further, the clampengagement mechanism 312 can be attached to the handle 310 through hinge504. Further, handle 310 and the body 306 can be attached by a pair ofhinges 506/508 that couple a pivot arm 510 between them.

As shown, the handle 310, clamp engagement mechanism 312, body 306, andpivot arm 510 all pivot with respect to one another, and no sliding isperformed. In some embodiments, pivot arm 510 can act as an input link.In some embodiments, clamp engagement mechanism 312 can act as an outputlink. In some embodiments, one of the input/output links can spin allthe way around, if not obstructed, and the other can rock back and forththrough a given angular range. Further, the handle 310 can act as afloater link, which can drive the input link to a position where therocker link just begins to rock back and further movement of the inputis obstructed by the body of the linkage, which can be a self-energizingtoggle point. The body 306 can act as the ground link (or fixed link).In some embodiments, the grounded links can rotate though a limitedrange of angles which does not include 0° or 180°.

FIG. 15C shows an embodiment of the bow hanger 300 in an open position.As shown, the clamp engagement mechanism 312 can be pulled away fromattachment member 302, thus allowing for the rail 102 to be insertedbetween them. Once the bow hanger 300 is in the proper position on therail 102, the user can apply a force (upward in FIG. 14C) onto thehandle 310, thus closing bow hanger 300 onto the rail 102. This attachesthe rail 102 to the truck bed 100. Also, as shown in FIG. 15C, the body306 can be configured to move or slide along and independently ofconnecting member 500. This movement can facilitate avoidance of anyobjects in the storage position, and can facilitate attachment to therail 102. The body 306 can be locked into a particular position on theconnecting member 500, and can be unlocked to move along the connectingmember 500. This can be done through a locking mechanism or throughfrictional forces, and the type of locking does not limit thedisclosure.

Rotation Configuration

FIGS. 16-19 show an embodiment of the bow hanger 300 wherein members302/308 can rotate within body 306. This can allow for the bow hanger300 to be rotated out of the way into a stow position so that the bowhanger 300 is not damaged when the tonneau cover is removed and foldedfor storage, thereby making it less likely that the bow hanger 300 isdamaged. In some embodiments, the body 306, handle 310, and clampengagement mechanism 312 can be rotated to be generally parallel withthe axis of the rail 102. In some embodiments, attachment member 302/308can be rotated approximately 45, 50, 60, 70, 80, 90, 100, 110, 120, 130,140, 150, 160, or 180 degrees in body 306. In some embodiments,attachment member 302/308 can be rotated less than approximately 45, 50,60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, or 180 degrees inbody 306. In some embodiments, attachment member 302/308 can be rotatedgreater than approximately 45, 50, 60, 70, 80, 90, 100, 110, 120, 130,140, 150, 160, or 180 degrees in body 306.

FIG. 20 illustrates an embodiment of the rotation mechanism of the body306. The figure shows a cross section of the body 306 along theconnecting member 500 which connects members 302/308.

FIG. 21 illustrates another cross section of the body 306 along theconnecting member 500 which connects members 302/308. This view showsthat two different pieces of the body 306, as discussed above, can beattached by an engagement mechanism 601. Further, FIG. 21 shows member308 inserted into bow 200.

The connecting member 500 can have a generally circumferential slot 602around the outside. At one end of the slot 602 can be a divot 604extending into the center of the connecting member 500. The body 306 caninclude a tab 606 configured to reside in the slot 602. When theconnecting member 500 is rotated to a maximum rotation, the tab 606 willbe located within divot 604. This divot 604 can releasably hold the tab606 so that the connecting member 500 will remain in the rotatedposition unless a force is applied to release the tab 606. In someembodiments, the tab 606 can be formed from a generally flexiblematerial, though the type of material does not limit the disclosure. Insome embodiments, the body 306 is configured to slightly bow outward toallow translation of the tab 606 within the slot 602. In someembodiments, the slot 602 can contain a plurality of divots 604, therebyallowing for mechanical stop points along the path of the slot 602.FIGS. 22-23 illustrate further cross-sectional viewpoints.
